It is now possible for upto 2 players to start in Extra Galactic Clusters

Note that I have NOT tested this extensively!

One player takes the main EGS civic, the 2nd player takes the 2nd Civic "multiplayer Extra Galactic Start", it has the default grey icon (and is sorted alphabetically).

It should be obvious, but do not take the multiplayer civic outside of multiplayer with a player 1 taking the main civic.

The main civic player makes most of the choices. Their decisions are restricted somewhat:

Spawning constellation is limited to apprentice or antronach.
Spawning system is limited to sol, deneb or ring world
Kerbals are disabled

Whatever other settings they choose apply to both players (gigastructures, connectivity).
Whichever constellation they don't pick, player 2 gets. So the play is always apprentice and antronach constellations.

Player 2 can pick their starting system, that's it.
Player 2's move happens on day 3, to avoid player 1's

If player 1 enables the other extra galatic clusters and enabled a ring of wormholes, then the player in the apprentice cluster always links to steed, and the player in antronach always links to big dipper.

It does not matter who is hosting for who takes the origin.

I have no intention of supporting additional clusters or players, as the amount of code increases geometrically.
